I guess my problem was not running Gnome3 - I was running a bare Xsession session with openbox window manager. I logged out, then logged in with a Gnome3 Unity session, and update-manager is working OK for me and downloading and applying changes. So for me the but is that update-manager does not work in an Xsession (when I ran it there, I never got a password prompt for the sudo behavior).
(I still don't know why 'sudo apt-get update' failed as that should not need any gui components) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/819328 Title: [Oneiric] update-manager crashed with DBusException in _run(): org.freedesktop.DBus.Error.NoReply: Did not receive a reply.
